The electric car can turn on the electricity, but the car does not go.
Should be caused by line problems, virtual or short circuit collision.Check the line related accessories, including air switch, fuse, controller interface, battery wiring, one by one investigation and repair in a timely manner.If you have any problems, you can only go to the maintenance shop to check the three major items, including motors, controllers, batteries.
4. Slow motor speed(1) cause of failure: speed change, turn damage. Lack of battery capacity or charge. The controller is out of order. The motor is out of order. (2) troubleshooting detecting speed hand speed signal line (green line) turn on voltage, maximum angle, speed voltage should be 4.2V. If less than this voltage, will cause the electrode speed is slow, should change the speed control handle. Recharge the battery. Replace the controller or motor. 5. Motor jitter (brushless)(1) cause of trouble: motor Holzer connector bad. Turn the contact bad. There is interference in the speed signal line. (2) Troubleshooting: first, the motor Holzer connector is not good, re inserted. Turn the contact bad, re insert. Disturb the speed signal line, change the controller and instrument. The vibration of the electric bicycle during use is caused by the bad contact between the motor Holzer switch, the connector and the switch connector. Therefore, the focus of inspection connectors, especially the motor Holzer switch connector.
2. When the motor is stopped(1) the cause of the fault is that the voltage of the battery is in the critical state of under voltage. Battery contact is bad. The speed control switch to wire breaking is not broken. Breakdown of brake power off switch. The power supply lock is damaged and the contact is bad. The line connector plug side. The controller component welding is not strong. (2) Troubleshooting: check the battery voltage and supply the battery. Adjust or change the plug. Reconnect the speed control and turn the lead. Adjust or change the brake power off switch. Switch the power lock. The re inserted line. The replacement of the controller. The replacement of the motor.3. Car without electricity(1) the cause of the trouble is that the fuse tube is burnt out. Battery damage. The battery breaker line. The power lock is broken. Battery contact or plug contact is bad. Troubleshooting: (2) using a multimeter voltage blocking detection output voltage of the battery, such as no voltage, check the fuse tube and fuse holder, battery, battery connecting wire has no circuit, such as battery output voltage is normal, check the power supply controller input voltage, such as voltage, check whether the electric door lock and cable breaking and plug bad.
Line heating, indicating that the car has a short-circuit phenomenon, or your line is too thin, this is certainly. Wired to burn large chunks of leather, it should be wired. Common faults and removal methods of electric vehicles1. Not a bit(1) the causes of damage the brake fault judgment speed control switch to damage the motor damage judgment the judge controller damage (2) trouble shooting out the brakes to socket (normally open type brake handle). For example, when the motor is running, the brake handle shall be replaced by the brake handle. Turn the voltage of the source 5V normal, detect the signal voltage, turn to turn, the signal voltage should be from 0.8 to 4.2V, from low to high. If there is no change in voltage and less than 1V, the switch is turned or the circuit is short circuited. If the voltage is greater than 1V and the change is normal, check the motor Holzer signal (yellow, green and blue lines). If the three-phase Holzer signal line voltage is all 5V, and good contact, then the motor Holzer damage, should replace the motor or motor Holzer components. Third, the motor Holzer signal line is detected, and the motor is rotated slowly by hand. Each phase voltage should change between 0 and 5V. If there is no change in the voltage, the motor is damaged by Holzer, and the motor or motor Holzer component should be replaced. If the voltage of each phase is changed normally and the power supply is normal, the controller is damaged and the controller is replaced.
